Insufficient information to answer with any confidence, but here's a thought experiment to help decide: say that your cluster was divided into separate machines -- each node was running properly, but they were entirely unable to communicate with each other, and indeed didn't know that each other *existed*, but whatever front end you have feeding information *into* the cluster (say, a load balancer) still knew about all of them and was continuing to send data to each, probably semi-randomly. Would the application still work correctly?
The above situation is basically the pathological extreme of what can happen with auto-downing turned on -- the cluster slowly decomposes into individual nodes, each of which thinks that it is the entire cluster. In most cases, the answer is "no", because if it was "yes", you probably didn't need Akka Clustering in the first place. But I don't know how your application works...
